WebWhen more than two genes are being considered, the Punnett-square method becomes unwieldy. For instance, examining a cross involving four genes would require a 16 × 16 grid containing 256 boxes. It would be extremely cumbersome to manually enter each genotype. For more complex crosses, the forked-line and probability methods are preferred. WebApr 9, 2024 · Figure 12.3. 3: The forked-line method can be used to analyze a trihybrid cross. Here, the probability for color in the F 2 generation occupies the top row (3 yellow:1 green). The probability for shape occupies the second row (3 round:1 wrinked), and the probability for height occupies the third row (3 tall:1 dwarf). WebThe fork line method can be used by figuring the occurrence of each gene or set of genes to be found in the gamete, and then multiply them together. This can be multiplied by figuring each trait or combination of traits separate for both the male and female, or each … oregon child support statistics
